The problem is when one spouse gives 100% all the time for many years and you then realize the other is a Narcissus. Burn out takes place quickly and you are just being used and abused. Nothing she needs will ever be fulfilled because she is lost in her childness needs that a parent did not give and the spouse is not her parent and does not have any power to fix her emotional past. She will never grow up and no prayers can change that persons responsibility for themselves not addressing their own past. They cannot give in their marriage and children what they do not possess.
And when you see that same aspect of lack of accountability in their siblings, there is not much hope of it ever changing. As they all protect the false believes they live even when claiming to be catholic.
